While I love Jackbot, it isn't a system 11 game.
F14 Tomcat is a necessity for a System 11 game collection. It's when pinballs got FAST. So fast that all the mechanisms kept breaking, and they had to build stronger parts because the EM-Compatible parts that used to survive years of play got destroyed by F14!
High speed is a lot more fun than you remember. It has this pulsing 'dun-dun-dun-dun' sound when the siren is about to get started that gets your pulse racing every time.
My friend James had a favorite game, and that was "Rock-Rock-Rockin' Rollergames'. Speed, interesting shots, unusual theme, challenging and fun playfield layout. For years I've felt that this game is just a bit underappreciated.
I like the 'complete the challenge' games. Taxi and Diner and Riverboat Gambler (magic!) are strongly goal-oriented, and if that's the kind of play that brings you joy, they would be really high on your list.
Elvira may be the best of the System 11 games. Some real magic here.
For my personal play, I like BK2000, but I wouldn't suggest it as the best of the system 11's... it's just hard enough for my personal skill level to make me keep coming back to it.
If you get Mousin' Around, put the back legs on 4x4 blocks to raise the playfield pitch as high as possible. Mousin' around becomes an astonishing play experience when it's set to too much playfield pitch. It's... 'peppy'.
You really can't go wrong, this is the first wave when pinballs got good... before the 90's when pinballs got REALLY good, starting with Funhouse.
For me, BK2000 would be top, but that's for me. For you?
EATPM, F14 and High Speed are top tier system 11's. Depending on your personal taste, most anything else is going to make you really happy.
This is a quick list that may not be complete pulled from the pinball list and price guide book from 2018, and the numbers are ROUNDED and MAY NOT BE ACCURATE, and you should buy their book if you want their real numbers.
